VPS With Predefined Resources

Our module allows you to offer OpenStack VPS to your clients in two ways, with predefined resources and configurable resources.

In this section we will show you configuration of VPS with predefined resources.
Detailed information about configuration of VPS with resources chosen by client can be found here.

VPS With Configurable Resources

21. Preparing VPS with configurable options consists of pressing 'Generate default' as shown on the following screen.

It will prepare default configurable options which can be afterwards easily edited as described in this article.
Important Configurable option 'flavor|Flavor' will be overwritten by 'disc|Disc' , 'ram|RAM' and 'vcpus|VCPUs' .
Therefore, you can solve this in three ways:

  • Remove 'disc|Disc' , 'ram|RAM' and 'vcpus|VCPUs' configurable option and rely completely on 'flavor|Flavor' .
  • Remove 'disc|Disc' and 'vcpus|VCPUs' , and allow 'flavor|Flavor' being overwrited by 'ram|RAM' (multiple combinations allowed here).
  • Remove 'flavor|Flavor' and rely completely on 'disc|Disc' , 'ram|RAM' and 'vcpus|VCPUs' .

Note: The second and the third options causes a new flavor being made on your server each time a new order is made.

OSV20.png
Congratulations! You have just finished the installation and configuration of the module with configurable resources.

Ordering

Owing to configurable options, you are able to offer product which your clients can tailor according to their needs.

Additionally, you are able to set up pricing for each configurable option, which make your offer even more competitive.
Important: VPS is not created immediately after ordering 'Create' . Therefore, it is wise to inform your clients about the delay.

Module allows your customers to easily start/stop, pause/unpause, resume, soft reboot, hard reboot and reset network of their servers through pressing specified button.
Clients can also rebuild the server, access noVNC console, create a backup and view scheduled tasks.
At 'Tasks' your customers can view all requested tasks that was not yet completed.
Each task has additional information bounded to them, like type of task, attempts to perform tasks or last returned response.

OSV26.png

On the following screen you can view exemplary topology of such network.

OSV36.png
Second type of network is a network with floating IP address.

Tips

1. Due to some requests may take time to be completed, we implemented 'Scheduled Tasks' .

Tasks visible at 'Scheduled Tasks' are subsequently performed by cron job.
Full list of tasks supported by 'Scheduled Tasks' are: create, terminate, change package, remove IP address and remove backup.

2. Important: module has to use admin endpoints instead of public endpoints.

In properly configured OpenStack server, wget from WHMCS server should be able to get any data from any admin endpoint.
Sample successfull requests:

wget openstack:9292
--2014-03-31 09:35:24-- http://openstack:9292/
Resolving openstack(openstack)... 192.168.1.222

wget openstack:8777

Connecting to openstack(openstack)|192.168.1.222|:8777... connected.
HTTP request sent, awaiting response... 401 Unauthorized
Authorization failed. 
3. A primary IP address is always assigned by OpenStack server when a VM is created Therefore, if you decide to order 2 IP addresses, then 3 addresses will be assigned.
The primary one and the two additionally ordered. If you wish only one IP address to be assigned to a single product, please set the filed 'Default Number Of IP Addresses' to '0'
or leave it empty in the product's 'Module Settings'.

Common Problems

1. When you have problems with connection, check whether your SELinux or firewall does not block ports.
2. 'Connection Error: No route to host' error.

Reason: WHMCS server can not resolve OpenStack endpoint hostnames.
Solution: Log in to your OpenStack via SSH and use 'keystone endpoint-list' command to obtain list of needed endpoints.

OSV 41.png
Afterwards, check each URL from 'adminurl' column using 'ping' command at your WHMCS server.

All URLs which are not reachable have to be added to 'hosts' file on a server with your WHMCS.

3. In case of persisting connection problems, please make sure you have the following ports open:
8774, 35357, 9292, 5000, 8777, 9696, 8776
